Ground rules: earth, chassis, and signal ground
However, "ground" as a concept can be confusing as it relates to three different situations: chassis ground, signal ground, or earth ground. All three indicate connecting to a point of (theoretically) zero voltage, but within a different context: chassis ground for a device, signal ground for very low voltage signals within a device, and earth …
Get PriceCampervan Leisure Batteries
A V.L.A battery is a type of lead-acid battery used to store and supply power. These types of batteries are the most common type found in a campervan. The battery itself is non-sealed, which allows both hydrogen and oxygen (a by-product produced from charging) to vent freely into the atmosphere.

The concepts of grounding techniques, earthing, making PCB ground connections, and PCB chassis ground are all very convoluted in electronics, despite international standards that have tried to separate concepts and terminology. Grounding is important in every aspect of electronics design, electrical work, and of course, in PCB …
Get PriceSeven Ways To Supply Power to a Breadboard
When doing prototype work with breadboards for a project, the question comes up "how to power the breadboard?" at the very start. Therefore, a power supply must be chosen that fulfills the requirements of the specific project. There exist a wide range of different alternatives to provide power to a breadboard. Each alternative has different […]

Should you connect a DC power supply to ground or not? The answer is not a straightforward yes or no. This article explores the benefits and drawbacks of grounding DC power supplies.
Get Pricepower supply
You may connect the minus point of several batteries to the same ground, you may have different strings of batteries connected in series. If you know for sure that the 5 V supply is floating, you may connect both minus points together regardless if the 12 V supply is grounded or not.
Get PriceCan I have two different voltage sources use the same ground? : …
The positive connection of the 1.34V power supply is also the negative connection to your 12.06V power supply so you can''t really have them in the circuit at the same time if they are both positive supplies and they share a ground. I''m guessing the illegal
Get PriceConnecting grounds together
After looking at a couple of wiring diagrams for various circuits, I noticed it seems quite common to wire the grounds of different power supplies together. E.g. for an LED strip, which draws power from a separate power supply but is controlled with a data pin from the Arduino, the ground of the LED power supply is fed through two ground …

Get PriceWhere is the Ground in a Simple Electronic Circuit [duplicate]
Traditionally, "ground" is the lowest potential in a circuit, e.g. the minus side of a battery or DC supply. In an AC circuit, such as the 110 volts AC coming into your house (at least in the US), ground will be the wire closest to the earth potential (i.e. you can usually touch the white wire, which is the ground or neutral wire, but get a bad shock if …

Ground is merely a label. It is a logical point in the circuit relative to which you measure all other voltages against. For instance the 5V pin on the Arduino is actually 5V relative to the ground pin. A 12V battery''s + …

If the receiver doesn''t have very good power supply rejection/filtering that noise can end up in its output signal. I would disconnect the receiver''s VCC (leave ground connection as-is) and power it from a battery. Does that solve it: then VCC is the issue. If …
Get PriceCar Audio Myth – You Can''t Ground a Car Audio Amplifier to the Battery
The installer can bolt the ground lead from the amp to the chassis, then run a conductor of the same size as the power leads to the battery''s negative terminal. In this scenario, the worst-case condition is that the new ground wire carries all the current from the amp, and you have a minimal voltage drop.

I''m using a separate power supply for the steppers (6V). I''m looking forward to expand the system to 3 up to 10 motors. Now i have read that i should share the grounds so i have connected the ground of the Arduino (powered from the USB cable) with the ground
Get Price"Ground" vs. "Earth" vs. common vs. negative terminal
For low power systems, especially battery-powered systems, ground can be completely detached from any connection (physical or otherwise) to physical earth. But any electrical or electronic circuit, whether it''s in a plane, or a car, or even in outer space, needs a reference point to start from in describing voltages and currents, and that …

Get PriceNegative Effects of Grounding (Earthing) a DC Power Supply
Current leakage from power supplies to earth ground can result in unwanted breaker tripping, if too many power supplies are used together. Image used courtesy of Canva In one power supply, this will only result in a tiny amount of current, as the leakage through a capacitor is very small (less than a milliamp).
